Abstract: The present invention relates to a fixed brake caliper (1) for a disc brake disc (2), - said disc (2) comprising opposite braking surfaces (3, 4) and axial-symmetric disc body (5) adapted to rotate about a rotation axis (A-A) defining an axial direction (X-X), said disc body (5) develops radially along a radial direction (R-R) orthogonal to said axial direction (X-X), as well as along a circumferential direction (C-C) orthogonal both to said axial direction (X-X) and to said radial direction (R-R); said fixed caliper (1) comprising: a first half-body (6) comprising at least one first housing (7) for a first thrust device (8) to generate a first braking action; said first half-body (6) being adapted to face either directly or indirectly a first braking surface (3) of said braking surfaces (3, 4) of said disc (2); a second half-body (9) comprising at least one second housing (10) for a second thrust device (11) to generate a second braking action; said second half-body (9) being adapted to face either directly or indirectly a second braking surface (4) of said braking surfaces (3, 4) of said disc (2); at least one first bridge element (12) to connect and support said second half-body (9) to said first half-body (6); said at least one bridge element (12) comprising at least one first guiding and supporting bridge surface (13) oriented according to a first predetermined resting plane (14) and at least one second guiding and supporting bridge surface (15) oriented according to a second predetermined resting plane (16); wherein said first half-body (6) comprises at least one first protrusion (17) which protrudes in a cantilevered manner in axial direction (X-X) towards the opposite second half-body (9); said second half-body (9) comprises at least one second protrusion (18) which protrudes in a cantilevered manner in axial direction (X-X) towards the opposite first half-body (6); said first half-body (6), said second half-body (9) and said at least one bridge element (12) are three mutually separable components; and wherein said at least one first protrusion (17) delimits a first guiding and resting half- body surface (19) oriented according to said first predetermined resting plane (14) and parallel to said at least one first bridge surface (13) when said bridge element (12) is connected to said first half-caliper (6); said at least one second protrusion (18) delimits a second guiding and resting half-body surface (20) oriented according to said second predetermined resting plane (16) and parallel to said at least one second bridge surface (15) when said bridge element (12) is connected to said second half-caliper (9); said at least one bridge element (12) firmly rests said at least one first bridge surface (13) thereof against said first half- body surface (19) by connecting and orienting said at least one bridge element (12) to said first half-body (6), creating a rest for said at least one bridge element (12) in circumferential direction (C-C); said at least one bridge element (12) firmly rests said at least one second bridge surface (15) thereof against said second half-body surface (20) by connecting and orienting said at least one bridge element (12) to said second half-body (9) in circumferential direction (C-C).
